To get a clear diamond colored more or less like the classical PlantUML entity colors. This code works individually but when combined with entities I get "Syntax Error?"

In any case, I would really appreciate some help with this.

I am currently taking a class in databases and we have to draw ER diagrams. I would much rather use your software (which is amazing btw) then "Astah UML", which is the one recommended by the professor.
